Filed: 1987-11-11
Abstract: PURPOSE:To eliminate the need for precision registration of both Si substrates and a substrate for forming an optical integrated circuit at the time of assembling by providing a hollow groove having a nearly perpendicular wall near the end part of a light guide. CONSTITUTION:A perpendicular groove or hole 4 of about the same depth as the depth of an optical fiber fixing groove 3 is formed in the end part before or after the formation of the fixing groove. The perpendicular groove 4 formed in the end part of the V-groove 3 forms the perpendicular wall in the end of the light guide 1 simultaneously when the 111 face of end part is removed and, therefore, the gap between the optical fiber 2 and the light guide 1 is eliminated and the coupling efficiency between both is greatly improved. The stable and high-efficiency coupling is thus obtd. simply by fixing the optical fiber 2 into the V-groove 3. The freedom from adjustment at the time of assembling various kinds of waveguide type optical elements is thereby enabled.

Title: Nozzle head for introducing liquid into storage tank
Inventor: YANO SEIJI
IPC: B05B3/06
Filed: 1990-10-22
Abstract: PURPOSE:To easily and surely agitate a tank when a liq. is introduced into the tank by providing an injection nozzle opened in the direction offset from the radial direction to the rotating shaft of a nozzle base. CONSTITUTION:A liq. such as heavy oil is introduced into a nozzle head 4 through an inlet pipeline member 2 and injected into a tank 1 from the orifice 6b of a first injection nozzle 6 and the orifice 7b of a second injection nozzle 7. Since the orifice 6b of the first injection nozzle 6 is opened in the direction offset from the radial direction to the rotating shaft of a nozzle base 5, the head 4 tends to rotate in direction of the arrow A. The liq. is injected from the orifice 7b of the second nozzle 7 having a relatively small diameter in the direction generating a force against the rotation of the head 4 in direction of the arrow A. However, the injection force of the second nozzle 7 resists the rotation of the head 4, hence the head 4 is rotated at an appropriate speed, and the liq. is injected from the nozzles 6 and 7 with an appropriate injection force.

Title: Bright annealing method for metal having high affinity for oxygen
Inventor: EBNER PETER
IPC: C21D9/67
Filed: 1999-10-05
Abstract: PROBLEM TO BE SOLVED: To avoid surface defects in an annealing material, as protective gas, by using rare gas pure as much as possible in such a manner that it is acted cooperatively with an oxygen bonding body. SOLUTION: Preferably, for subjecting metal adhered with a remaining lubricant to bright annealing, the lubricant is evaporated under protective gas composed of rare gas or inert gas and/or reducing gas, and, as protective gas for the subsequent bright annealing, rare gas mixed with <=50 vol.% reducing gas and pure as much as possible is used in such a manner that it is acted cooperatively with an oxygen bonding body. As the protective gas, pure rare gas such as argon, neon or the like is used in such a manner that it is acted cooperatively with an oxygen bonding body, advantageously with Ti. By using the protective gas together with the oxygen bonding body in an annealing case, the reaction accompanying the oxidation or discoloration is checked by an oxygen carrier such as CO, CO2, H2O or the like or oxygen.  Moreover, the transport of the oxygen and oxygen carrier from a heat resistant material of the annealing case to the annealing material is generally blocked.

Abstract: PROBLEM TO BE SOLVED: To reduce friction resistance of a chain between itself and a chain guide or a tensioner, generate uniformly a load share along a link train, reduce a cost, and facilitate manufacture and assembly, in a silent chain. SOLUTION: Several link plates 170 in a low back part height, which is a height between a horizontal line connecting an opening hole center and the highest point on an outer side surface, and several link plates 180 in a high back part height are combined, to be arranged. During operation, since only the link plate 180 in a high back part height is slid on a chain guide or a tensioner, friction resistance between a chain and the chain guide or the tensioner can be reduced. A thickness t2 of the link plate 170 is larger than a thickness t1 of the link plate 180. In this way, rigidity of both the link plates 170, 180 is made roughly equal, a load share along a link train can be uniformly generated.
